Good evening, does anyone know which grommets work best for the spark plug wires going through the Airform baffles on an O-470 182b? Getting to that point and don’t seem to find just the right ones.
Thank you.

Maybe these from Aircraft Spruce - Slick M2375 5mm

I don’t think those will work, holes are 1 1/16” in diameter. One per cylinder.

Dunno about C182B, but C180 & C185 generally used MS35489-12 grommets and the spec indicates such grommet has
.062 inch groove width
.375 inch dia. hole
1.000 inch groove dia.
1.250 inch outside dia.
.250 inch thick

Thanks got it!

I wasn’t even close
